Capacitor sizing for power factor correction
1 unit air-compressor ( 3 phase 415 VAC ) used an average of 90 kW with an existing power factor of 80%.The desired power factor is 95%. The factor value for this case is 0.421 to raise the power factor from 80% to 95% using table 1. 0.421 x 90 kW = 38 kVAR. So we need capacitor size 38 kVAR to get power factor 95% for 1 unit air …
